“If you enter the right code, then you’re number displays visually on the display on the front of the screen, so you can use it for your online and you’re over the phone purchase,” said Mullen. “And it writes the stripe magnetically, so you can use it in a store.”

A touch of a button reveals the security code needed for online or telephone purchases.

“After a period of time, the display erases and the strip erases. So, if you lose the card or it’s stolen, it’s irrelevant. It’s a dead piece of plastic,” Mullen added.

If your local retailer gets hacked, a la Target, and your card number cyber flies to the black market on the other side of the world, Mullen says “it could not be used again because the actual code changes with each purchase.”

Negotiations with banks and providers to launch the cards are ongoing, but Mullen is confident the hidden card will join the success of its ePlate card, which allows you to designate two rewards providers per card.
